GF91.60-P-4001-03SK Driver Airbag, Design

Design of 2-stage driver airbag
^ The driver airbag unit is bolted to the multifunction steering wheel (MFL) and upholstered on the side facing the driver. The upholstery is equipped with a predetermined fracture point to enable the airbag to deploy fully.
^ The casing contains the inflator, which is equipped with 2 acid-free solid fuel units and is connected to the airbag by way of a filter. The solid fuel units are connected to driver airbag squib 1 (R12/13) and driver airbag squib 2 (R12/14) so that they can be ignited.
^ The electrical connection between driver airbag squib 1 (R12/13) and driver airbag squib 2 (R12/14) from the MFL to the restraint systems control unit (N2/7) is made via the steering column module (N80).
^ In order to avoid unintentional triggering, driver airbag squib 1 (R12/13) and driver airbag squib 2 (R12/14) are equipped with short-circuit bridges that short-circuit the connections automatically if the coupling is broken.
